I don't see why Buzzfeed are being criticised for it either, because they only reported verified facts - that the report was going around, that it was neither verified or falsified, that it contained errors and falsehoods. I imagine the others are just annoyed Buzzfeed jumped first when they all had it so they're criticising them.
"By some definition", sure. I have no idea what the definition of fake news is (I just made a comment saying I have no idea what it is at this point), but I expect that some definitions being used would include buzzfeed yep.
